Abstract (en)
[origin: EP1939661A1] The invention relates to a lens unit and a lens driving apparatus, which enable lenses to be displaced smoothly without increasing a restriction on a distance between the lenses and moreover, prevent positioning accuracy of the lenses from decreasing. First to third guide members (25 to 27) have first to third axis lines (31 to 33), and the first to third axis lines (31 to 33) are arranged in parallel with each other. A first lens holder (28) has a first lens (35) held by a first lens holding portion (35) with a first main sliding portion (37) guided by sliding on the first guide member (25), and a first sub sliding portion (38) guided by sliding on the third guide member (27). A second lens holder (29) has a second lens (45) held coaxially with the first lens (35) by a second lens (45) holding portion with a second main sliding portion (47) guided by sliding on the second guide member (26), and a second sub sliding portion (48) guided by the third guide member (27).
